Here is a simple exercise.
Take a piece of paper and write down the following phrase…
“What Great Thing Would I do If I Knew I Could Not Fail?”
Underneath the phrase write down five to ten things that would fit the description.
Look at the items and imagine in your mind that you could accomplish them in the next 24 hours.
What one thing sticks out on the list that would have the most impact?
Circle this one thing.
Here is the start of a long term goal.

Good stuff. Actually reminds me of the approach Eisner took w/some of his projects in helping to break down some of the limitations we put on ourselves. By framing the question this way you really open yourself up to all the opportunities available.
For goal setting you might try out this web-based application:
Gtdagenda.com
You can use it to manage your goals, projects and tasks, set next actions and contexts, use checklists, schedules and a calendar.
A mobile version is available too.
As with the last update, now Gtdagenda has full Someday/Maybe functionality, you can easily move your tasks and projects between “Active”, “Someday/Maybe” and “Archive”. This will clear your mind, and will boost your productivity.
Hope you like it.
